Clinical Efficacy and Gut Microbiota Regulating-Related Effect of Si-Jun-Zi Decoction in Postoperative Non-Small Cell Lung Cancer Patients: A Prospective Observational Study.

BACKGROUND: Postoperative non-small cell lung cancer (NSCLC) patients frequently encounter a deteriorated quality of life (QOL), disturbed immune response, and disordered homeostasis. Si-Jun-Zi Decoction (SJZD), a well-known traditional Chinese herbal formula, is frequently employed in clinical application for many years. Exploration is underway to investigate the potential therapeutic effect of SJZD for treating postoperative NSCLC. OBJECTIVE: To assess the efficacy of SJZD on QOLs, hematological parameters, and regulations of gut microbiota in postoperative NSCLC patients. METHODS: A prospective observational cohort study was conducted, enrolling 65 postoperative NSCLC patients between May 10, 2020 and March 15, 2021 in Yueyang Hospital, with 33 patients in SJZD group and 32 patients in control (CON) group. The SJZD group comprised of patients who received standard treatments and the SJZD decoction, while the CON group consisted of those only underwent standard treatments. The treatment period was 4 weeks. The primary outcome was QOL. The secondary outcomes involved serum immune cell and inflammation factor levels, safety, and alterations in gut microbiota. RESULTS: SJZD group showed significant enhancements in cognitive functioning (P = .048) at week 1 and physical functioning (P = .019) at week 4. Lung cancer-specific symptoms included dyspnea (P = .001), coughing (P = .008), hemoptysis (P = .034), peripheral neuropathy (P = .019), and pain (arm or shoulder, P = .020, other parts, P = .019) eased significantly in the fourth week. Anemia indicators such as red blood cell count (P = .003 at week 1, P = .029 at week 4) and hemoglobin (P = .016 at week 1, P = .048 at week 4) were significantly elevated by SJZD. SJZD upregulated blood cell cluster differentiation (CD)3+ (P = .001 at week 1, P < .001 at week 4), CD3+CD4+ (P = .012 at week 1), CD3+CD8+ (P = .027 at week 1), CD19+ (P = .003 at week 4), increased anti-inflammatory interleukin (IL)-10 (P = .004 at week 1, P = .003 at week 4), and decreased pro-inflammatory IL-8 (P = .004 at week 1, p = .005 at week 4). Analysis of gut microbiota indicated that SJZD had a significant impact on increasing microbial abundance and diversity, enriching probiotic microbes, and regulating microbial biological functions. CONCLUSIONS: SJZD appears to be an effective and safe treatment for postoperative NSCLC patients. As a preliminary observational study, this study provides a foundation for further research.

[Effects of salt stress on bacterial community composition and diversity in rhizosphere soil of Bletilla striata]. / ç›èƒè¿«å¯¹ç™½åŠæ ¹é™ ç»†èŒç¾¤è½ç»„æˆåŠå¤šæ ·æ€§çš„å½±å“.

Salinization environment affects the normal growth and development of plants, as well as the microbial community in the rhizosphere. To explore the succession dynamics of bacterial communities in the rhizosphere soil of Bletilla striata under salt stress condition, we performed 16S rRNA high-throughput sequencing to determine the bacterial community composition and diversity of B. striata in the rhizosphere under different salt stress concentrations, measured the effects of salt stress on the growth and development of B. striata and soil physicochemical pro-perties, and analyzed the correlation between community composition of rhizosphere bacteria and the soil environmental factors. The results showed that compared with the control, salt stress reduced growth rate and health degree of B. striata, and significantly decreased the content of soil organic matter, nitrogen and phosphorus. Under the salt stress treatment, species diversity and evenness of the bacterial communities in the rhizosphere of B. striata showed a trend of first decreasing and then increasing. There were significant differences in the relative abundance and variation trends of the dominant bacterial taxa in the rhizosphere soil of B. striata at the phylum and class levels between the control and the salt stress treatments. Salt stress intensity and duration were important factors affecting bacterial community composition in the rhizosphere soil of B. striata. Soil organic matter, available nitrogen, and total phosphorus content were key environmental factors affecting the structure of rhizosphere bacterial community composition. Functional genes related to cytoskeleton, cell motility, substance metabolism and signal transduction mechanisms may be involved in the adaptation and stress response of bacterial communities to salt stress. This study would provide theoretical basis and reference for the cultivation management of B. striatain saline area.

Predicting the mechanism of action of YQYYJD prescription in the treatment of non-small cell lung cancer using transcriptomics analysis.

ETHNOPHARMACOLOGICAL RELEVANCE: The efficacy of the herbal formula Yiqi Yangyin Jiedu (YQYYJD) in the treatment of advanced lung cancer has been reported in clinical trials. However, the key anti-lung cancer herbs and molecular mechanisms underlying its inhibition of lung cancer are not well-understood. AIM OF THE STUDY: To identify the key anti-lung cancer herbs in the YQYYJD formula and investigate their therapeutic effect and potential mechanism of action in non-small cell lung cancer (NSCLC) using transcriptomics and bioinformatics techniques. MATERIALS AND METHODS: A mouse Lewis lung carcinoma (LLC) subcutaneous inhibitory tumor model was established with 6 mice in each group. Mice were treated with the YQYYJD split formula: Yiqi Formula (YQ), Yangyin Formula (YY), and Ruanjian Jiedu Formula (RJJD) for 14 days. The tumor volume and mouse weight were recorded, and the status of tumor occurrence was further observed by taking photos. The tumor was stained with hematoxylin-eosin to observe its histopathological changes. Immunohistochemistry was used to detect the expression of the proliferation marker Ki67 and the apoptotic marker Caspase-3 in tumor tissues. Flow cytometry was used to detect the number of CD4+ and CD8+ T cells and cytokines interleukin-2 (IL-2) and interferon-gamma (IFN-γ) in the spleen and tumor tissues. The differential genes of key drugs against tumors were obtained by transcriptome sequencing of tumors. Gene Ontology (GO) and Kyoto Encyclopedia of Gene and Genomes (KEGG) enrichment analyses were performed on differential genes to obtain pathways and biological processes where targets were aggregated. TIMER2.0 and TISIDB databases were used to evaluate the impact of drugs on immune cell infiltration and immune-related genes. The binding activity of the key targets and compounds was verified by molecular docking. RESULTS: YQ, YY, and RJJD inhibited the growth of subcutaneous transplanted tumors in LLC mice to varying degrees and achieved antitumor effects by inhibiting the expression of tumor cell proliferation, apoptosis, and metastasis-related proteins. Among the three disassembled prescriptions, YQ better inhibited the growth of subcutaneous transplanted tumors in LLC mice, significantly promoted tumor necrosis, significantly increased the expression of Caspase-3 protein in tumor tissue, and significantly decreased the expression of Ki-67 (P < 0.05), thereby increasing the infiltration of CD8+ T cells. YQ significantly increased the expression of CD4+ and CD8+ T cells in tumor and splenic tissues of tumor-bearing mice and up-regulated the expression of IL-2 and IFN-γ. Transcriptome sequencing and bioinformatics results showed that after YQ intervention, differentially expressed genes were enriched in more than one tumor-related pathway and multiple immune regulation-related biological functions. There were 12 key immune-related target genes. CONCLUSION: YQ was the key disassembled prescription of YQYYJD, exerting significant antitumor effects and immune regulation effects on NSCLC. It may have relieved T cell exhaustion and regulated the immune microenvironment to exert antitumor effects by changing lung cancer-related targets, pathways, and biological processes.

Determination of the total antioxidant capacity of the Chinese tea based on a novel "peroxidase/zirconium phosphonate"composite electrochemical sensor.

In this work, a novel zirconium phosphonate (ZrPR1R2) was prepared by decorating both the aminoethoxy- group (R1) and the carboxypropyl- group (R2) on the zirconium phosphate layers in order to manipulate further the immobilization of the peroxidase (POD), and an antioxidant biosensor with higher sensitivity was constructed by dropping the POD/ZrPR1R2 composite onto the glassy carbon electrode surface. The activity of the POD/ZrPR1R2 composite was detected by Uv-vis spectra. The direct electrochemical behavior, the electrocatalytic response to dissolved oxygen and hydrogen peroxide, as well as the ability to detect total antioxidant capacity in tea sample were investigated by the methods of cyclic voltammetry. The results indicated that the immobilization of POD in ZrPR1R2 nanosheets matrix enhanced the enzymatic activity, and achieved the fast and direct electron transfer between POD and glassy carbon electrode. Moreover, the POD/ZrPR1R2 composite modified electrode show the electrocatalytic response to hydrogen peroxide in the linear range of 8.8×10-8 to 8.8×10-7 mol L-1, with the detection limit of 3.3×10-8 mol L-1. Attributing to the sensitive response to dissolved oxygen, the total antioxidant capacity can be detected directly in the real tea water by this POD/ZrPR1R2 composite modified electrode.

Electrically-assisted anaerobic digestion under ammonia stress: Facilitating propionate oxidation and activating methanogenesis via direct interspecies electron transfer.

Electrical assistance is an effective strategy for promoting anaerobic digestion (AD) under ammonia stress. However, the underlying mechanism of electrical assistance affecting AD is insufficiently understood. Here, electrical assistance to AD under 5 g N/L ammonia stress was provided, by employing a 0.6 V voltage to the carbon electrodes. The results demonstrated remarkable enhancements in methane production (104.6 %) and the maximal methane production rate (207.7 %). The critical segment facilitated by electro-stimulation was the microbial metabolism of propionate-to-methane, rather than ammonia removal. Proteins in extracellular polymer substances were enriched, boosting microbial resilience to ammonia intrusion. Concurrently, the promoted humic/fulvic-substances amplified the microbial electron transfer capacity. Metagenomics analysis identified the upsurge of propionate oxidation at the anode (by e.g. unclassified_c__Bacteroidia), and the stimulations of acetoclastic and direct interspecies electron transfer-dependent CO2-reducing methanogenesis at the cathode (by e.g. Methanothrix). This study provides novel insights into the effect of electrical assistance on ammonia-stressed AD.

Study on the difference and regularity of tongue images in 309 patients with different pathological stages of non-small cell lung cancer.

BACKGROUND: Tongue diagnosis is a crucial traditional Chinese medicine (TCM) inspection method for TCM syndrome differentiation and treatment. OBJECTIVE: The primary research focus was on tongue image characteristic parameters of patients with non-small cell lung cancer (NSCLC). Analysis of the tongue image parameters of various pathological stages of NSCLC provides technical support for establishing an integrated Chinese and Western auxiliary diagnosis and efficacy evaluation medicine system for lung cancer that integrates tongue image features. METHODS: Tongue image characteristics of 309 patients with NSCLC and 206 controls were collected and analyzed clinically. The T-test or rank sum test and logistic regression analysis were applied to analyze the characteristics of tongue image indicators of different pathological stages of NSCLC. RESULTS: There were differences in tongue image characteristics in the NSCLC group compared to the control group. The tongue quality and brightness of the tongue coating in the NSCLC group increased, the red component was reduced, the tongue coating thickened, and the yellow component increased compared to the healthy control group. A comparison of tongue image indexes of NSCLC in different pathological stages showed that stage IV had lower TB-b and higher TB-a than stage I. In addition, stage IV had lower TB-b than stage II + III, showing an increase in the blue and red components of the tongue in stage IV and the appearance of cyanotic tongue features. CONCLUSION: The tongue image characteristics of NSCLC patients differed from those of the control group. Tongue imaging indicators can reflect the characteristics of tongue images of patients with NSCLC. The tongue image characteristics of patients with stage IV lung cancer are bluish and purple compared with those with stage I, II, and III. It is suggested that the tongue's image characteristics can be used as a reference for the pathological classification of NSCLC and judgment of the disease process.

Qilian Formula Inhibits Tumor Cell Growth in a Bone Metastasis Model of Lung Cancer.

BACKGROUND: Bone metastasis is frequently common in advanced lung cancer with the major issue of a pathological fracture. Previous studies suggested that Astragalus membranaceus (Qi) and Ampelopsis japonica (Lian), which are used as folk medicine in China, have potential effects on inhibiting tumor growth and protecting bones, respectively. In this study, an experiment on the inhibitory effect of the Qilian formula (AAF) in vivo was designed to examine tumor growth in bone and osteoclast formation. MATERIALS AND METHODS: The bone metastasis xenograft models were established by implanting NCI-H460-luc2 lung cancer cells into the right tibiae bones of mice. After confirming the model's viability through optical imaging 7 days post-implantation, 2 groups, namely the AAF group and the control group, were administered 0.3 mL of AAF extract (9 g/kg/day) or normal saline via intragastric delivery for a duration of 4 weeks. Throughout the study, we longitudinally assessed tumor burden, bone destruction, and weight-bearing capacity in vivo using reporter gene bioluminescence imaging (BLI), micro-CT, and dynamic weight-bearing (DWB) tests. Mechanistic insights were gained through Hematoxylin-eosin (H&E) staining, immunohistochemical (IHC) analysis, western blotting, and flow cytometry. RESULTS: Qilian formula produced significant inhibition to the progress of bone destruction and tumor burden in the right tibiae bone in the treatment group. It was further evidenced by molecular imaging in vivo via small animal micro-CT and BLI with parametric quantification, characterizing significantly lower uptake of BLI signal in the treated tumor lesions and improving the pathological changes in the microstructure of bone. Furthermore, DWB tests revealed that Qilian formula treatment significantly maintained the weight-bearing capacity. According to immunohistochemical analysis, the effect of the Qilian formula appeared to involve the suppression of osteoclast formation by lower expression of the tartrate-resistant acid phosphatase. Cell apoptosis and death induction were evidenced by a higher percentage of Bal2、BAX and caspase 3 expressions of Qilian formula-treated tumor tissues. CONCLUSIONS: Our study demonstrated a significant inhibitory effect of the Qilian formula on the progression of osteolytic invasion in vivo by suppressing osteoclastogenesis and promoting apoptotic cell death.

Establishment of a multicomponent quality control method and the transfer characteristics of five markers from Qidongning Formula to rat tissues by HPLC-QQQ-MS/MS.

Introduction: Traditional Chinese medicine compound preparations have become an increasingly utilized strategy for tumour treatment. Qidongning Formula (QDN) is a kind of antitumour compound preparation used in hospitals, and it can inhibit the growth of lung cancer cells. However, due to the complexity of botanical drugs, the quality evaluation of QDN is inconsistent, affecting clinical efficacy and posing potential safety risks for clinical application. Additionally, tissue distribution is an integral part of the drug development process. Methods: To study the distribution characteristics of markers in compound preparations and rat tissues, a novel HPLC-QQQ-MS/MS quantitative analytical method was established to determine five markers in QDN simultaneously, and the method was verified. Results and discussion: The analytical results showed that the contents of salidroside (51.6 ± 5.75 µg/g), calycosin-7-O-ß-D-glucoside (94.2 ± 15.4 µg/g), specnuezhenide (371 ± 72.5 µg/g), formononetin (23.8 ± 5.39 µg/g), and polyphyllin I (87.7 ± 10.6 µg/g) were stable in different batches of QDN. After intragastric administration (13.5 g/kg) in rats for 1 h, four markers in the QDN, except polyphyllin I, were distributed in most tissues. QDN was distributed chiefly in the stomach and small intestine, followed by the liver or kidney. The study also found that specnuezhenide had the highest concentration in both QDN and rat tissues (102 ± 22.1 µg/g in the stomach), while formononetin had the highest transfer rate (0.351%) from QDN to rat intestines. The above research lays a quality research foundation for the antitumour application of QDN and provides a scientific reference for the quality control of Chinese medicine compound preparations.

Insights into accumulation of active ingredients and rhizosphere microorganisms between Salvia miltiorrhiza and S. castanea.

Salvia miltiorrhiza is an important traditional herbal medicine, and its extracts could be used for treating cardiovascular disease. Although these medicinal compounds are functionally similar, their wild relative, S. castanea, produces significantly different concentrations of these compounds. The reason for their differences is still unknown. In a series of soil and plant-based analyses, we explored and compared the rhizosphere microbiome of S. miltiorrhiza and S. castanea. To further investigate the geographical distribution of S. castanea, MaxEnt models were used to predict the future suitable habitat areas of S. castanea in China. Results revealed the distributions and structure of the rhizosphere microbial community of S. miltiorrhiza and S. castanea at different times. In addition, differences in altitude and soil moisture resulting from changes in climate and geographical location are also critical environmental factors in the distribution of S. castanea. The findings of this study increase our understanding of plant adaptation to their geographical environment through secondary metabolites. It also highlights the complex interplay between rhizospheric factors and plant metabolism, which provides the theoretical basis for the cultivation of S. miltiorrhiza and the use of S. castanea resources.

Background: Acupuncture and moxibustion has been applied worldwide in the treatment of various pain diseases including lumbar disc herniation (LDH) and other pain, However, there has been no bibliometric analysis on this aspect in the past five years. Therefore, this study was carried out for finding research trends and fronts in this field using Citespace and VOSviewer. Methods: Publications about acupuncture therapy for LDH were extracted from the Web of Science database and PubMed with an unlimited time frame. A bibliometric analysis and visualization of results was conducted using CiteSpace 6.1.R3 and VOSviewer 1.6.18 on the information of the annual publication, countries, journals, institutions, authors, references, and keywords. Results: A total of 127 publications were included, and the number of publications had increased noticeably over the past 30 years and reached a peak in the past 3 years. The most productive country with the most publications was China, whose Medical University was the institution with the highest volume of publications. The most productive author was Chen Rixin, while the most-cited author was Kreiner DS. Chinese Acupuncture and Moxibustion was the journal with the most publications, and Spine Journal was the most frequently cited journal. In cited references, an article published in The New England Journal of Medicine by Deyo RA had the most citations and the highest centrality. Of the keywords, the five most frequently used keywords include lumbar disc herniation, acupuncture, low back pain, intervertebral disc displacement, and management. Conclusion: Acupuncture and moxibustion can help to relieve symptoms in patients. However, this field is in the early stages of development and requires more high-quality research studies and international collaborations. In addition, exploring the effectiveness and mechanism of acupuncture for LDH is the hot trend in the future.

[Mechanism of Marsdenia tenacissima against ovarian cancer based on network pharmacology and experimental verification].

The present study aimed to explore the main active components and underlying mechanisms of Marsdenia tenacissima in the treatment of ovarian cancer(OC) through network pharmacology, molecular docking, and in vitro cell experiments. The active components of M. tenacissima were obtained from the literature search, and their potential targets were obtained from SwissTargetPrediction. The OC-related targets were retrieved from Therapeutic Target Database(TTD), Online Mendelian Inheritance in Man(OMIM), GeneCards, and PharmGKB. The common targets of the drug and the disease were screened out by Venn diagram. Cytoscape was used to construct an "active component-target-disease" network, and the core components were screened out according to the node degree. The protein-protein interaction(PPI) network of the common targets was constructed by STRING and Cytoscape, and the core targets were screened out according to the node degree. GO and KEGG enrichment analyses of potential therapeutic targets were carried out with DAVID database. Molecular docking was used to determine the binding activity of some active components to key targets by AutoDock. Finally, the anti-OC activity of M. tenacissima extract was verified based on SKOV3 cells in vitro. The PI3K/AKT signaling pathway was selected for in vitro experimental verification according to the results of GO function and KEGG pathway analyses. Network pharmacology results showed that 39 active components, such as kaempferol, 11α-O-benzoyl-12ß-O-acetyltenacigenin B, and drevogenin Q, were screened out, involving 25 core targets such as AKT1, VEGFA, and EGFR, and the PI3K-AKT signaling pathway was the main pathway of target protein enrichment. The results of molecular docking also showed that the top ten core components showed good binding affinity to the top ten core targets. The results of in vitro experiments showed that M. tenacissima extract could significantly inhibit the proliferation of OC cells, induce apoptosis of OC cells through the mitochondrial pathway, and down-regulate the expression of proteins related to the PI3K/AKT signaling pathway. This study shows that M. tenacissima has the characteristics of multi-component, multi-target, and multi-pathway synergistic effect in the treatment of OC, which provides a theoretical basis for in-depth research on the material basis, mechanism, and clinical application.

SLC5A3 is important for cervical cancer cell growth.

Novel molecular targets for cervical cancer must be identified. This study examined the role of SLC5A3, a myo-inositol transporter, in the pathogenesis of cervical cancer. Through boinformatics analysis, we showed that the SLC5A3 mRNA levels were upregulated in cervical cancer tissues. The upregulated SLC5A3 mRNA levels were negatively correlated with survival and progression-free interval. Genes co-expressed with SLC5A3 were enriched in multiple signaling cascades involved in cancer progression. In primary/established cervical cancer cells, SLC5A3 shRNA/knockout (KO) exerted growth-inhibitory effects and promoted cell death/apoptosis. Furthermore, SLC5A3 knockdown or KO downregulated myo-inositol levels, induced oxidative injury, and decreased Akt-mTOR activation in cervical cancer cells. In contrast, supplementation of myo-inositol or n-acetyl-L-cysteine or transduction of a constitutively active Akt1 construct mitigated SLC5A3 KO-induced cytotoxicity in cervical cancer cells. Lentiviral SLC5A3 overexpression construct transduction upregulated the cellular myo-inositol level and promoted Akt-mTOR activation, enhancing cervical cancer cell proliferation and migration. The binding of TonEBP to the SLC5A3 promoter was upregulated in cervical cancer. In vivo studies showed that intratumoral injection of SLC5A3 shRNA-expressing virus arrested cervical cancer xenograft growth in mice. SLC5A3 KO also inhibited pCCa-1 cervical cancer xenograft growth. The SLC5A3-depleted xenograft tissues exhibited myo-inositol downregulation, Akt-mTOR inactivation, and oxidative injury. Transduction of sh-TonEBP AAV construct downregulated SLC5A3 expression and inhibited pCCa-1 cervical cancer xenograft growth. Together, overexpressed SLC5A3 promotes growth of cervical cancer cells, representing as a novel therapeutic oncotarget for the devastating disease.

Exploring the mechanisms of self-made Kuiyu Pingchang recipe for the treatment of ulcerative colitis and irritable bowel syndrome using a network pharmacology-based approach and molecular docking.

BACKGROUND: Ulcerative colitis (UC) and irritable bowel syndrome (IBS) are common intestinal diseases. According to the clinical experience and curative effect, the authors formulated Kuiyu Pingchang Decoction (KYPCD) comprised of Paeoniae radix alba, Aurantii Fructus, Herba euphorbiae humifusae, Lasiosphaera seu Calvatia, Angelicae sinensis radix, Panax ginseng C.A. Mey., Platycodon grandiforus and Allium azureum Ledeb. OBJECTIVE: The aim of the present study was to explore the mechanisms of KYPCD in the treatment of UC and IBS following the Traditional Chinese Medicine (TCM) theory of "Treating different diseases with the same treatment". METHODS: The chemical ingredients and targets of KYPCD were obtained using the Traditional Chinese Medicine Systems Pharmacology database and analysis platform (TCMSP). The targets of UC and IBS were extracted using the DisGeNET, GeneCards, DrugBANK, OMIM and TTD databases. The "TCM-component-target" network and the "TCM-shared target-disease" network were imaged using Cytoscape software. The protein-protein interaction (PPI) network was built using the STRING database. The DAVID platform was used to analyze the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Using Autodock Tools software, the main active components of KYPCD were molecularly docked with their targets and visualized using PyMOL. RESULTS: A total of 46 active ingredients of KYPCD corresponding to 243 potential targets, 1,565 targets of UC and 1,062 targets of IBS, and 70 targets among active ingredients and two diseases were screened. Core targets in the PPI network included IL6, TNF, AKT1, IL1B, TP53, EGFR and VEGFA. GO and KEGG enrichment analysis demonstrated 563 biological processes, 48 cellular components, 82 molecular functions and 144 signaling pathways. KEGG enrichment results revealed that the regulated pathways were mainly related to the PI3K-AKT, MAPK, HIF-1 and IL-17 pathways. The results of molecular docking analysis indicated that the core active ingredients of KYPCD had optimal binding activity to their corresponding targets. CONCLUSION: KYPCD may use IL6, TNF, AKT1, IL1B, TP53, EGFR and VEGFA as the key targets to achieve the treatment of UC and IBS through the PI3K-AKT, MAPK, HIF-1 and IL-17 pathways.

Effects of music therapy on anxiety in patients with cancer: study protocol of a randomised controlled trial.

INTRODUCTION: Although music therapy (MT) has been found to reduce anxiety in patients with cancer and delay tumour progression to some extent, its mechanism of action has not been determined. MT may reduce anxiety by reducing the concentrations of proinflammatory cytokines. The present study was designed to evaluate the effects of MT on anxiety and cytokine levels in patients with cancer. METHODS AND ANALYSIS: This randomised, open, single-centre parallel-controlled trial will randomise 60 patients with malignant tumours who meet the inclusion criteria in a 1:1 ratio to either an MT group or a non-MT (NMT) group. Patients in the MT group will receive emotional nursing care and individualised receptive MT for 1 week, whereas patients in the NMT group will receive emotional nursing care alone. Primary outcomes will include scores on the State-Trait Anxiety Inventory, Distress Thermometer and Hamilton Anxiety Scale. Secondary outcomes will include scores on the Quality of Life Questionnaire C30, serum concentrations of the cytokines interleukin (IL)-1ß, tumour necrosis factor-α, IL-2R, IL-4, IL-6, IL-8 and IL-10, serum concentrations of the neurotransmitters 5-hydroxytryptamine, dopamine, norepinephrine, adrenocorticotropic hormone and γ-aminobutyric acid, and determination of gut microbiota populations. ETHICS AND DISSEMINATION: On 5 August 2020, the study protocol was approved by the Research Ethics Committee of the Yueyang Hospital of Integrated Traditional Chinese and Western Medicine of the Shanghai University of Traditional Chinese Medicine. The findings of this study will be published in peer-reviewed publications and presented at appropriate conferences. TRIAL REGISTRATION NUMBER: CTR2000035244.

Transcriptomic and Metabolomic Changes Reveal the Immunomodulatory Function of Casein Phosphopeptide-Selenium Chelate in Beagle Dogs.

Casein phosphopeptide-selenium chelate (CPP-Se) is an organic compound produced by the chelation of casein phosphopeptide with selenium. This compound showed the ability to modulate canine immune response in our previous study; but its effect on the peripheral blood transcriptome and serum metabolome was unknown. This study aims to reveal the potential mechanism behind the immunomodulatory function of CPP-Se. We have identified 341 differentially expressed genes (DEGs) in CPP-Se groups as compared to the control group which comprised 110 up-regulated and 231 down-regulated genes. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis found that DEGs were mainly involved in immune-related signaling pathways. Moreover, the immune-related DEGs and hub genes were identified. Similarly, metabolomics identified 53 differentially expressed metabolites (DEMs) in the CPP-Se group, of which 17 were up-regulated and 36 were down-regulated. The pathways mainly enriched by DEMs were primary bile acid biosynthesis, tryptophan metabolism, and other amino acids metabolic pathways. Combined analysis of transcriptomic and metabolomic data showed that the DEGs and DEMs were commonly enriched in fatty acid biosynthesis, pyrimidine metabolism, glutathione metabolism, and glycerolipid metabolic pathways. Taken together, our findings provided a theoretical basis for further understanding of the immunomodulatory function of CPP-Se as well as a scientific reference for the future use of CPP-Se in pet foods as a dietary supplement to modulate the immunity.

Efficacy of intense pulsed light therapy on signs and symptoms of dry eye disease: A meta-analysis and systematic review.

This study reviewed the efficacy and safety of intense pulsed light (IPL) for the treatment of dry eye disease (DED). The PubMed database was used to conduct the literature search, which used the keywords "intense pulsed light" and "dry eye disease". After the authors evaluated the articles for relevancy, 49 articles were reviewed. In general, all treatment modalities were proven to be clinically effective in reducing dry eye (DE) signs and symptoms; however, the level of improvement and persistence of outcomes differed amongst them. Meta-analysis indicated significant improvement in the Ocular Surface Disease Index (OSDI) scores post-treatment with a standardized mean difference (SMD) = -1.63; confidence interval (CI): -2.42 to -0.84. Moreover, a meta-analysis indicated a significant improvement in tear break-up time (TBUT) test values with SMD = 1.77; CI: 0.49 to 3.05. Research suggests that additive therapies, such as meibomian gland expression (MGX), sodium hyaluronate eye drops, heated eye mask, warm compress, lid hygiene, lid margin scrub, eyelid massage, antibiotic drops, cyclosporine drops, omega-3 supplements, steroid drops, and warm compresses along with IPL, have been found to work in tandem for greater effectiveness; however, in clinical practice, its feasibility and cost-effectiveness have to be taken into consideration. Current findings suggest that IPL therapy is suitable when lifestyle modifications such as reducing or eliminating the use of contact lenses, lubricating eye drops/gels, and warm compresses/eye masks fail to improve signs and symptoms of DE. Moreover, patients with compliance issues have been shown to benefit well as the effects of IPL therapy is sustained for over several months. DED is a multifactorial disorder, and IPL therapy has been found to be safe and efficient in reducing its signs and symptoms of meibomian gland dysfunction (MGD)-related DE. Although the treatment protocol varies among authors, current findings suggest that IPL has a positive effect on the signs and symptoms of MGD-related DE. However, patients in the early stages can benefit more from IPL therapy. Moreover, IPL has a better maintenance impact when used in conjunction with other traditional therapies. Further research is needed to assess cost-utility analysis for IPL.

Antagonizing EZH2 combined with vitamin D3 exerts a synergistic role in anti-fibrosis through bidirectional effects on hepatocytes and hepatic stellate cells.

BACKGROUND AND AIM: Whether vitamin D3 (VD3) supplementation is associated with improved liver fibrosis is controversial. METHODS: Liver fibrosis models were treated with VD3, active VD (1,25-OH2 Vitamin D3), or collaboration with GSK126 (Ezh2 inhibitor), respectively. Hepatic stellate cells (HSCs) were co-cultured with hepatocytes and then stimulated with TGF-ß. Autophagy of hepatocytes was determined after the intervention of 1,25-OH2 Vitamin D3 and GSK126. Also, the active status of HSCs and the mechanism with 1,25-OH2 Vitamin D3 and GSK126 intervention were detected. RESULTS: 1,25-OH2 Vitamin D3, but not VD3, is involved in anti-fibrosis and partially improves liver function, which might be associated with related enzymes and receptors (especially CYP2R1), leading to decreased of its biotransformation. GSK126 plays a synergistic role in anti-fibrosis. The co-culture system showed increased hepatocyte autophagy after HSCs activation. Supplementation with 1,25-OH2 Vitamin D3 or combined GSK126 reduced these effects. Further studies showed that 1,25-OH2 Vitamin D3 promoted H3K27 methylation of DKK1 promoter through VDR/Ezh2 due to the weakening for HSCs inhibitory signal. CONCLUSIONS: VD3 bioactive form 1,25-OH2 Vitamin D3 is responsible for the anti-fibrosis, which might have bidirectional effects on HSCs by regulating histone modification. The inhibitor of Ezh2 plays a synergistic role in this process.

D Rhamnose ß-hederin Reverses NAP1L5-mediated Adriamycin Resistance in Breast Cancer.

Context: The persistent use of anticancer medicines can cause multidrug resistance in many tumors and serious cytotoxicity for healthy cells, including adriamycin (ADR), a treatment for breast cancer (BC). Cell resistance to ADR in patients with recurrent advanced BC can occur. Creating effective treatments that can grapple with multidrug resistance is still challenging. Traditional Chinese medicine (TCM) may offer a solution in D Rhamnose beta-hederin (DRß-H), an oleanane type of triterpenoid saponin. Objective: The study intended to assess the ability of DRß-H to inhibit the ADR resistance of two BC-lineage cell lines, MCF-7 and SUM-1315, and to explore the causal link between DRß-H and the reversal of chemoresistance. Design: The research team performed a cell biology study. Setting: The study took place at laboratory in China. Outcome Measures: The research team: (1) assessed cell viability and the migration and invasion the cell lines; (2) investigated the molecular mechanism and identified the downstream targets of DRß-H, and (3) comprehensively examined the expression pattern, underlying functions, and evident prognostic significance of NAP1L5 in BC by gathering the online information available. Results: DRß-H can inhibit the viability of the MCF-7/ADR and SUM-1315/ADR cancer cells in a dosage-dependent manner. NAP1L5 might be the main target of DRß-H in reversing ADR resistance. Its expression decreased in BC cells, and the more advanced the BC was, the lower the NAP1L5 expression was. Conclusion: DRß-H at nontoxic concentrations was related to ADR resistance in BC through its downstream target NAP1L5. NAP1L5 is potentially a preferable prognostic marker for BC.

Managing Severe Evaporative Dry Eye with Intense Pulsed Light Therapy.

INTRODUCTION: This study assessed the efficacy and safety of intense pulsed light (IPL) therapy in participants with severe evaporative dry eye disease (DED). METHODS: This randomized, controlled, single-center study included 49 adult participants (≥ 18 years) with severe evaporative DED who received either IPL therapy (n = 56 eyes) or sham therapy (n = 42 eyes) three times. The primary efficacy parameters were ocular surface disease index (OSDI) score, non-invasive tear breakup time (NITBUT), tear film lipid layer (TFLL), conjunctivocorneal staining score (CS), MG Score, meibomian gland (MG) quality, and MG expression score. RESULTS: The mean ages for the IPL group and the control group were 28.05 ± 3.41 years (57.1% female) and 28.14 ± 3.53 years (52.4% female), respectively. Comparison between the IPL group and the control group found significant differences in the mean OSDI score (22.16 ± 6.08 vs. 42.38 ± 6.60; P < 00.01), NITBUT (6.27 ± 0.84 vs. 3.86 ± 0.68; P < 0.001), TFLL (2.14 ± 0.44 vs. 3.45 ± 0.50; P < 0.001), MG Score (1.34 ± 0.55 vs. 1.88 ± 0.33; P < 0.001), MG quality (1.59 ± 0.07 vs. 2.67 ± 0.08), and MG expression (1.54 ± 0.57 vs. 2.45 ± 0.55) at 12 weeks follow-up; however, there was no significant difference in CS (3.32 ± 1.11 vs. 3.74 ± 1.04; P = 0.063). CONCLUSION: The findings suggest that IPL therapy is clinically beneficial in ameliorating the signs and symptoms of severe evaporative dry eye disease.

Efficacy of acupuncture for endometriosis-associated pain: a multicenter randomized single-blind placebo-controlled trial.

OBJECTIVE: To evaluate the efficacy and safety of acupuncture in the treatment of endometriosis-associated pain. DESIGN: A multicenter, randomized, single-blind, placebo-controlled trial. INSTITUTIONS: Four tertiary hospitals in Jiangxi and Hainan Provinces. SUBJECTS: Women with endometriosis-associated pain aged between 20 and 40 years. INTERVENTION: Subjects were assigned randomly to receive either acupuncture or sham acupuncture treatment for 12 weeks, starting one week before each expected menstruation and administered as a 30-minute session once per day, 3 times a week. During the menstruation period, acupuncture was administered daily when pelvic pain associated with endometriosis occurred. After acupuncture or sham acupuncture treatment, the subjects were followed for another 12 weeks. MAIN OUTCOME MEASURES: Changes in maximum pain as assessed with the visual analog scale (VAS) for various pelvic pain, duration of dysmenorrhea, and scores on the Multidimensional Pain Inventory, Beck Depression Inventory, Profile of Mood States, and Endometriosis Health Profile from baseline to week 12 and week 24. RESULTS: A total of 106 women were assigned randomly to the acupuncture and sham groups. In the acupuncture group, the reduction in the dysmenorrhea VAS score was significantly greater after treatment, but not at the end of the trial, compared to the sham group. The duration of pain was significantly shorter in the acupuncture group. All test scores were improved to a significantly greater extent in the acupuncture group than in the sham group at week 12 but not at week 24. Changes in nonmenstrual pelvic pain and dyspareunia VAS scores were not different between the groups. No severe adverse events or differences in adverse events were recorded. CONCLUSION: Acupuncture is an effective and safe method of relieving dysmenorrhea, shortening the pain duration, and improving wellbeing and quality of life in women with endometriosis-associated pain, although its efficacy fades after treatment is discontinued.
